TxDOT must keep contract files for seven (7) years following closeout. Advance Funding Agreements, however, must be maintained indefinitely since these agreements may specify which parties are responsible for maintaining the roadway and/or certain facilities. Like most government information, these files are considered public information and are subject to open record requests. Refer to 43 TAC ch. 3, subch. B, to obtain TxDOT's rules regarding public information.
